Optical Cables - Developing For The Past Decades

Optical cables, sometimes called TOSLINK, are optical fiber cables which are commonly used for audio equipment nowadays

. Digital optical sockets in home theater setups and other audio electronics utilize such cables to carry audio signals to each other. These cables enables digital audio to be streamed from the source to the output hardware, enabling users to experience high quality and uncompressed digital audio.

S/PDIF standards have become the general standard for audio streaming. Gaming consoles and high definition multimedia players nowadays employ such sockets to enable high definition audio streams. Typically, audio signals go through decoders which then decodes these signals according to their formats. Because of this, high quality audio can be paired up with high definition videos and movies. Its speed has also greatly improved over the past years, now able to transmit signals even faster.

As it was first released to the public in 1983, optical cables only carried speeds of up to 3.1 Mbit/second. Nowadays, because of huge improvements, they are able to transmit signals of up to 125 Mbit/second through these fiber optic cables.

Home theater setups at home generally have these digital optical cables for audio connections. Running from the source to the decoder, they usually need decoders to decode the audio signals to project surround sounds. They were then limited to 48 KHz at 20-bit. Nowadays, they are utilized to carry and support almost all audio formats. DTS and Dolby Digital are some of them.

A lot of manufacturers make these optical cables. Covered with resin and then covered with plastic jackets to make them stronger, these layers are not interferences to the fiber optic cable themselves; they merely protect the signals. Most of the time, glass or plastic fibers are manufactured to be thin and transparent, which then carries light. By decoding this light, audio can then be heard through speakers. Ends of these cables have a square-like connector which goes into these sockets.

Some computers nowadays have optical audio outputs so users can stream audio to their encoders and be heard in 5.1 or 7.1 sound systems. This enables home theaters to surface, with easy setup and installation for surround sound systems. Audio cards and even external sound processors can easily hook up to computers, effectively upgrading your rig's sound system to be able to stream high fidelity audio.

With the right cables and equipment, you can surely then enjoy exceptional audio right in the comforts of your home.
